Neurovascular coupling (NVC) is the perturbation of cerebral blood flow (CBF) to meet
varying metabolic demands induced by various levels of neural activity. NVC may be …

Standard practices for quantifying neurovascular coupling (NVC) with transcranial Doppler
ultrasound (TCD) require participants to complete one-to-ten repetitive trials. However …

Cognitive testing with transcranial Doppler ultrasonography (TCD) has been used to assess
neurovascular coupling (NVC), but few studies address its multiple contributions …

Objective Neurovascular coupling (NVC) represents the increase in regional blood flow
associated with neural activity. The aim here was to describe a new approach to non …

Background Neurovascular coupling (NVC) can be assessed using transcranial Doppler
(TCD) measured task-activation of cerebral blood flow velocity (CBFv). However, not all …

Background We tested the hypothesis that paradigms from the Addenbrooke's Cognitive
Examination (ACE-III), including those that had not been studied using TCD previously …

Cerebrovascular dysfunction occurs early in dementia and can be identified by transcranial
Doppler ultrasonography (TCD). Few studies have examined cerebral blood flow velocity …

Understanding how the brain allocates resources to match the demands of active neurons
under physiological conditions is critically important. Increased metabolic demands of active …

Neurovascular coupling (NVC) is the matching between local neuronal activity and regional
cerebral blood flow (CBF), but little is known about the effects of age and sex on NVC. This …

Background The concept of neurovascular coupling has been postulated since the late
1800s and has been demonstrated most commonly in humans using visual stimuli (eg …
